I just got a ThinkPad T510 with Windows 7 Professional and I installed Daemon Tools Lite, but I keep getting an error when I run it:

Unable to add adapter.

I can't load iso images, because there is no virtual drive. I tried starting it as an administrator, it tried to update the virtual devices, and it got the same problem. Does anybody know how to fix this?

Thanks for that, although you might have gone a little overboard. Windows 7 64-bit - All I had to do was install the latest version of SPTD (64-bit) manually, then re-install Daemon Tools and the problem was solved. No messing around in the registry needed.
